well known dog trainer, Wayne Curry, accidently kills employee while filming safety video using live ammo

8. Maybe an expert can answer, WHY is it "useful"?

Meaning, this idiot (me, Army veteran, but that was a LONG time ago) thinks blanks would produce the same effect - same sound and everything - as live ammo. I guess the difference would be the sound of the projectile itself?

If it's really different, then why not load one bullet at a time, for EXACTLY this sort of reaction? ( meaning you fire the one bullet, the dog reacts, there isn't another bullet to be accidentally fired and go somewhere you didn't intend)

I just have to say this Curry guy is a stupid fucking idiot who should never be allowed to touch a gun again. (and that's the best case, assuming when all the evidence is in, people are convinced it truly was an "accident", a result of stupidity and carelessness)
